"unscaled" just keeps MRTG from adjusting the scale to make the graphs look
big--it doesn't change the values graphed.

It isn't clear to me if you are clear on the issue of "bytes" which MRTG
graphs (unless you tell it otherwise), and "bits" that some vendor
software use.

In case there is a "subjective" problem (it is not clear to me that there
is), I deal somewhat regularly with people who "know the network is
extremely busy", where MRTG, a Sniffer, and other tools all agree that it
is not (usually--I have to be carefule about getting cocky!).
